The elevation of every storey in a building is based upon ceiling height, floor thickness, and building product — through a basic average of around 14 feet. Not every level is thought about a storey: when a basement is usually thought about to it is in storey, a level there is no a roof (like a terrace or rooftop) is no technically a storey.

How high is a structure Storey?

Building story height varies extensively from just under the 14-foot median to well over it. That’s because several factors influence the storeys-to-feet conventional for a building: structure material, insulation type, and different elevation allowances for various levels.

Storeys within a structure aren’t required to it is in the very same height. Because that example, a structure lobby is often taller than the storeys above. Levels close to the top may have less floor area than those beneath. The larger base storeys and smaller height of the Willis Tower demonstrate this principle. Willis Tower incorporates design innovations that average it no require center columns for security — so there’s plenty of floor space for an monitoring deck and lots that family-friendly exhibits on the 109th floor to see how large Chicago yes, really is!

Story height is also minimal based on structure material and insulation thickness. Take a look at how max story elevation changes based on material:

Wood wall surface framing – Max storey height of 11 feet, 7 inches.Cold-formed steel wall framing – Max story height of 11 feet, 7 inches.Masonry walls – Max story height of 13 feet, 7 inches.Insulated concrete kind walls – Max story elevation of 11 feet, 7 inches; max unsupported wall surface height every story of 10 feet.Structural insulated panel walls – Max story height of 11 feet, 7 inches; bearing wall surface height every story that 10 feet.

Storey elevation by building Level

Although there space story elevation maximums for safety and security purposes, storeys come feet in ~ the same building can vary. How tall is a storey by structure level? How many feet in a storey can change depending top top story role and place within the building:

Top storey / Attic – At least 50% of the usable area must have ceilings of at least 7 feet.Mezzanine – A partial floor typically located halfway between the soil floor and 2nd floor.Main Floor/Lobby – In the joined States, we call the first floor the “ground floor.” In most of Europe, the “first floor” is actually the second level!Upper Ground – A key entrance floor around a meter over ground.Garden Level – A storey situated between a basement and first floor.Lower Ground – A storey two meters listed below ground, simply beneath the upper ground level.Basement – The section of a building in between two floor levels that is partly underground but has at least one-half the its height above pre-development soil level (natural grade).Crawl Space – A space at or below natural grade, frequently located between the joists that the floor above and the floor slab below, and height of 3.9 feet or less.Basement – A level v at the very least one-half that its height over average natural grade and also and height of at the very least 7.5 feet.Cellar – A storage level beneath lower ground level and also height that at the very least 7.5 feet.
